PUNCI-IING-BAG SUSPENSION HANGER.

Application filed May 10,

This invention relates to suspension devices for punching orfist-striking bags used in athletic exercise, especially for boxers orsparrers, and the object of the present improvement herein is to providestrong, flexible and extensible chain devices for suspending thestrike-bag before the user in "readily adjusted vertical position tosuit his height or stature and to meet the requirements as to lastingand wearing strength, as well as the greatly desired flexibility.

In the accompanying sheet of drawings- Figure 1 is a front elevation,showing a fragmentary portion of the upper end or tip of thepunching-bag; Fig. 2, a detached elevation, taken at right-angles toFig. 1, showing the suspension link-chain and stirrup, with the upperend of the said chain broken off Fig. 3, a vertical, central-section ofthe supporting-cup and. hollow bearingball, showing one form ofchain-suspension with adjusting means in said hollow bearing-ball, butomitting the punching-bag,

1 and having the lower end of the chain broken off; and Fig. 4:, a planview of the said bearing-ball showing the upper middlelink of the chainin section.

In these views 6 indicates the ordinary punching-bag (the upper, tipportion only being shown) having a suspending-loop 7.

8 indicates a circular disk or plate having a large orifice 9 thatextends downwardly in a deep, circular flange 10, the latter, in turn,having a lower external screw-thread 11 for the attachment of anorificed bottonrcap 12 that is internally screw-threaded and has a largecircular opening or orifice 13.

14 indicates a hollow bearing-ball, slightly more than hemispherical andhaving an open top 15, with a central orifice 16 in its bottom. Thisbearing-ball has a pivotal rolling-support in said orifice 13 whose edgeis beveled inwardly to properly accommodate said bearing-ball and form acircular axis therefor. r

17 indicates a circular washer arranged in the hollow bearing-ball andhaving a chain A extending downwardly through its central opening 18,such chain being made up of strong flat links a, a, and Z, the series oflinks a, a, being spaced twin or double outer ones and alternating witha single 1922.

course or series of spacing middle ones that are connected in suchseries by means of short horizontal pins or screws 0 that may be readilyremoved, to either lengthen or shorten the chain vertically, whendesired, and thereby suitthe height and reach of the user, and thensimply adding or removing one or more links, as the case may be.

At the upper end of the chain A, within the chamber provided by the deepflange 10 and the bottom-cap 12, is inserted a transverse. horizontalbolt or screw 19 having a pair of lock-nuts 20 thereon and extendingbeyond the opposite vertical sides of the outer links a, a, so as tohold the chain in suspended position from the bearing-ball 14, the saidwasher 17 forming a stop-platform within the ball for the upper end ofthe chain, and said bolt 19 allowing for longitudinal extension orcontraction of said chain to compensate for the varying heights of thoseusing the punching apparatus. Fig. 3 shows this chain A and itsadjusting structure very clearly, especially with the omission of thenear side-links of the twin series.

A stirrup 22 is attached, for free oscillatory movement, to the singlehalf-twisted plate link 24: at the lower end of chain A by means of thetransverse bolt or screw 23. The said stirrup 22 is removably-engaged bythe hereinbefore-named punching-bag loop 7.

I claim 2- In a punching-bag suspension-hanger device, the combinationof a punching-bag having attached thereto an upwardly-extendingsupporting-member, an overhead attaching-disk, a circularly-orificed cupdeta-chably-secured to the said disk, an opentop semispherical hollowbearing-ball journaled in saidorifice of the cup and having a. centralcircularly-orificed bottom, a flat centrally-orificed disk freelysupported and arranged within the said hollow bearingball, whose orificeis aligned with the centrally-orificed bottom of the bearing-ball, aflexible chain composed of alternating single and double plate-links andwith a punching-bag and said chain thence r0- jecting at its upper endthrough the ori ced bottom of said bearing-ball and the aligned internalfreely-supported orificed disk in 5 the bearing-ball, and' 'a transversebolt detachably-engaging any select one of the upper links of the chainwithin the said bearing-ball to adapt the chain to vertical longitudinalextension or contraction to suit differing heights and reaches of usersof the device, substantially as shown and described.
